Abstract:
One of the major difficulties when modeling any system are constraining the magnitude of the uncertainties. In oceanography, the uncertainties in the biogeochemical models regarding the planktonic contribution are significantly large. My research is focused on quantitatively investigating how diversity is responsible for a portion of those uncertainties, and identifying how the nature of the open ocean environment shapes diversity. Assessing diversity in the planktonic environment has historically been complicated and time-consuming, due to the high diversity and the tridimensional nature of the oceans. In the last few decades, high throughput systems are providing a wealth of data unrivaled by any research done up to this era. In this presentation, I will show how two sources of high-throughput data, molecular and semi-automated image techniques, are allowing us to deepen in our understanding of the interaction between diversity and open ocean function. To do so I will highlight two projects that show: 1) how the planktonic community is organized seasonally in the Sargasso Sea, how these communities respond to environmental parameters, and how this contributes to the regulation of the local biogeochemical cycles, especially to the biological pump, and 2) how the mesozooplankton community respond to latitudinal gradients and associated variation in environmental conditions. I will finally give some examples of other applications of how high-throughput genomic data, which helps us understanding how plankton populations are connected in the ocean, how they are responding to the warming of the oceans, and how we could link these data to modeling efforts in the oceans.
